[5] The Woodland Trust altered the format in 2016, introducing an additional round of voting to name a single tree of the year for the whole country.
[7] The four national competitions are run in September and October and ranking is determined by public vote on the Woodland Trust's website.
Nominations can be made by any individual or organisation by early August and a shortlist is compiled by a panel of independent experts to put forward to the public vote.
Each national winner receives a £1,000 grant from the People's Postcode Lottery to be used for any purpose in relation to the tree – this could range from a survey or health check, remedial works, plaques and signs or a celebratory event.
